To all whom it may concern: 7

Be it known that I, Josnrn MoOor, 'a citizen of the United States, and a resident of Minneapolis, in the county of Hennepin and State of Minnesota, have invented certain new and useful Improvements in Apparatus for Refrigeration, of which the following is a specification.

This invention relates to apparatus for forming ice in such manner that its heat absorbing qualities may be advantageously utilized without changing the location of the ice.

One object of'the invention is to provide, in a refrigerating apparatus, means whereby a low exterior temperature may be utilized for forming ice inside of a receptacle.

Another object of my invention is to provide, in combination with a cooling box, a heat absorbing mass formed at a distance therefrom in such manner that the heat absorbing mass will draw heat from goods placed in the cooling box.

Another object of my-invention is to provide means for cooling the interior of houses and the like by the heat absorbing qualities of a portion of the system positioned at a'point distant from the various rooms.

Another object of my invention is to provide means for regulatin thetemperatures of the various parts 0 the system.

, In the drawin Figure 1 is a conventional sectional side elevation of a house, showing in schematic form means for apply- -ing my refrigerating system. Fig. 2 is a sectional view of my refrigerator taken on the line 22, Fig. 4. Fig. 3 is a sectional view taken on the line 3--3, Fig. 2, and Fig. 4 is a sectional view taken on the line 4-4,

Figi 2.

y invention contemplates the use of a main refrigerator or heat absorbing means 1, Figs. 1 and 2, having two passageways 2 and 3 to the outside of the building wherein it is placed.

As the air on the exterior of the building in the cold season would be heavier than that on the interior, a circulation would be started in the direction indicated by the arrows 4, Figs. land 2, downwardly inside of the main refrigerator 1, and passing along below the vat 5 upwardly, as indicated by the arrows 6, and back to the outlet 2 in- 66 dicated by the arrows 7, as the incoming air would be warmed by the water or other fluid 8 contained in the vat 5;

In periods when the outside temperature was considerably below the freezing point of water, the fluid 8, if water was used, would be frozen by the free circulation of air along the circuit traced by the arrows, and thus a large heat absorbing medium established inside of the building.

To more readily freeze the liquids, flues 9 are provided in the vat, and to prevent the vat. bein broken .by the freezing of the liquids, t e bottom 10 is corrugated as are the sides-11, Fig. 3, while the sides 12, Fig. 4, are tapered, as shown, the corrugated sides allowing the expansion, and the tapered sides allowing the formed ice to move upwardly, in place of rupturing the vessel, while the fines 9, being circular and subject only to compression, are strong enough to take care of themselves.

An insulated closure 13 is provided to cut the system off from the outside air during the warm season, and the main refrigerator is well insulated, as shown in the drawings.

For a short period of time when the temperature of the outside air is above that of freezing, it is not necessary to close the door 13 as the action of the system is automatic in that the warm outside air will have no tendency to enter the channels 2 or 3 as it would have to displace the lower heavier air to enter the main refrigerator. 1

A secondary refrigerator 14, Fig. 1, is connected to the main refrigerator by 111911'.--' lated pipes or tubes 15and 16, the pipe-16" opening from the lower part of the main refrigerator to the lower part of the secondary refrigerator, and the pipe 15 leading from the upper part of the secondary refrigerator to the upper part of. the main refrigerator, thus insuring a circulation of air as indicated by the arrows 17 and 18. Adjustable dampers 19 and 20 are provided forregulating the amount of cold air passing through the pipes 15 and 16.

The secondary refrigerator 14 may be for the purpose of preserving food, as does the ordinary ice-box or refrigerator, or it may be in the form of a heat absorber, made in the style of the ordinary steam radiator, used to cool an entire room, in which case the walls would not be insulated but would absorb heat from the room and pass it up the pipe 15, as indicated by the arrows 18, 119

to the heatabsorbing mass in the main refri erator 1.

0 take care of the condensation thatmight occur in the refri erators, I provide a small drain Fig. 4, t rough which the condensed moisture may pass without allowing the loss of any appreciable amount of heat absorbing qualities of the main refrigerator, and this drain could lead through a form of water trap, if desired.

' With such a system of refrigeration it is possible, in portions of the country having a considerable period. of freezing-weather, to ',place a large main refrigerator in the attic of a building, form therein a large amount of ice, close off the outside air during the hot season of the year, and utilize a second- .ary refrlgerator for the entire hot season without conveying any ice into the house.

- Also, if the main refrigerator is of sufficient size, the house may be cooled by a series of heat absorbers, made in the style of ordinary radiators, or otherwise, placed in the different rooms, and this result accomplished without any expense, whatsoever, for

maintenance.

It is, ofcourse, evident that themain refrigerator could be placed in the basement, and the proper direction of circulation maintained by the use of fans, but I prefer, where practicable, to place the main refrigerator in the attic and utilize a purely thermal circulating system.

It will also be apparent to those skilled in the art that in place of having air circulate from the outside of the building through the main refrigerator and out again, it ispossi- 'ble to have a circulating system of brine, or

- the like, running from the outside of the building to the main refrigerator and thus cause the refrigeration by the circulation of brine through the pipes. V

This invention, however, contemplates broadly the circulating of any fluid, air, gas, or liquid from theexterior of a building to the interior for the purpose of storing up in .the building a heat absorbing mass to be used during the warm season of the year, as well as during the cold period. '50
